Abstract: Wireless sensor networks (WSN) are low cost, low power but highly effective platforms that have widespread applications in monitoring. WSNs are susceptible to some destructive attacks. Pairwise key pre-distribution design is essential for WSNs because of resource limitations in the physical sensor nodes. This paper presents symmetric design of combinatorial set system named projective plane in designing deterministic key pre-distribution for WSNs. First, a mathematical model for the networks under consideration is presented. Then, we sketch the various wireless network applications utilising connected dominating sets (CDSs). Then we propose a new model for reforming projective plane with key copying and exchanging based on CDS and virtual backbone. Performance and security properties of the proposed schemes are studied both analytically and computationally. Results show that the combinatorial and CDS-based virtual backbone approach produces better efficiency and resistance rate for sensor resiliency, resource efficiency, connectivity of the model and scalability in WSNs.
